Dynamic Reconfiguration

You do not need to restart the server for changes to certain configuration
files to take effect (for example, obj.conf, mime.types, server.xml, and virtual server-specific ACL
files). All you need to do is apply the changes by clicking the Apply link
and then clicking the Load Configuration Files button on the Apply Changes
screen. If there are errors in installing the new configuration, the previous
configuration is restored.

When you edit obj.conf and apply the changes, a new
configuration is loaded into memory that contains all of the information from
the dynamically configurable files.

Every new connection references the newest configuration. Once the last
session referencing a configuration ends, the now unused old configuration
is deleted.
